Last time you wrote "I can't walk on flat surfaces.My legs are going tight.However I can climb stairs easily." so you have experienced some improvement over the last few weeks if you can actually run up or down hill, as well as climb stairs now... "2.No problem while running,going uphill & downhill,stairs."
Though to be totally honest it doesn't make a lot of sense physically why you can run without a problem but can't walk slowly......if you are able to run, up and down hills, up and down stairs, it suggests everything mechanically speaking is working as it physically should be so it sounds to me like your probably dealing with a behaviourally (running?) related exacerbating or recurring injury eg irritation, inflammation, tear etc to the tendons, ligaments etc.
It's also possible your dealing with something like a Soleus muscle strain-injury, the soleus muscle can be overloaded when you are running uphill and or downhill. The soleus muscle runs from just below the knee to the heel and its purpose is to do with stability, standing and walking.
Honestly getting assessed by a physiotherapist might be a really good idea to help you work out what's causing this issue and they'd also provide you with appropriate stretching and recovery exercises etc As to your google induced health related anxiety and continual fears that what your experiencing could mean you have a condition like MS, ALS etc nothing you've mentioned (test evidence, symptoms etc) would be consistent or suggestive of these conditions, it would probably be a good idea to also see a psychologist or therapist to help you deal with your anxiety before it gets any worse and the anxiety takes over your life, it definitely can't hurt to be proactive and seek help specifically for your anxiety!
Hope that helps.....JJ
Try this. Have a glass of wine or a beer. If your slow walking improves, you most likely have limb dystonia. If not, disregard the following.
Reading, this you slow walking must improved. I am sorry. Yeah, the cerebral frontal lobe controls voluntary muscular movement. Sometimes an injury will cause a auto feedback which increases the neurological stimulation to the area of the brain.
When you’re at rest. the muscles are still tensing; you become stiff.
When you walk slowly, if feels like you’re walking in mud or through the Highwater. And the muscular movements that you’re doing or difficult to alter which he makes on even terrain difficult to manage.
When you move faster the muscles are not getting a chance to become stiff until your input stimuli of resting muscles or the muscles at rest accumulates to match the muscle you activate. Then you won’t be able to run.
Wine is a muscle relaxer that effect the he frontal lobe of cerebral hemisphere first.
I pray that you don’t have dystonia. This would mean injuries in other areas can duplicate the same effect. The etiology is unknown, but my 2 cents is betting on a peripheral injury that couples with spinal compression at do point to create a sensation to reproduce muscular activity. The etiology is undermined by the concept that the brain control voluntary movement; external stimuli and reflexes can cause the brain to respond. If the initiator isn’t disengaged, the brain will continue the loop.
If dystonia, stretching will lengthen your muscle to allow you more room before complete contraction or tetenus ( a severe spasm). If you’re spazzing, you may need muscle relaxer instead of self medicating with alcohol.
If dystonia, you will pay for the running when you stop because the resting neuro input is now higher; and stiffness will occur faster... or fuel is consumed, or potassium level have dropped. All will make movement more difficult.
As weird as it may sound maintain good posture; as you may have more than one injury. If dystonia, you need Gatorade and carnation instant breakfast to replace and rebuild losses.
Alcohol acts as a central nervous system depressant, the CNS is responsible for taking in information through the senses, motor function, emotion, thinking, understanding, reasoning etc etc etc. basically alcohol depresses the central nervous system making communication between the brain and the nerves slow down but alcohol affects just about every part of the brain and the nervous system...
The first area of the brain affected by even small amounts of alcohol is the cerebral cortex, which is why alcohol lowers inhibitions, and typically causes an initial increase in talkativeness and sociability etc, the affect alcohol has on Gamma- Aminobutyric Acid (GABA) is actually what makes alcohol the social lubricant. The next part of the brain alcohol is said to affect is the cerebellum, the cerebellum is the area of the hind brain that controls movement coordination, balance, equilibrium and muscle tone.
For all the obvious alcohol related dependency issues, consuming alcohol is not recommended for anyone to self medicate or as a diagnostic tool even when Dystonia is likely....I haven't a clue how Dystonia even came up to be honest, Vicky doesn't even mention experiencing anything resembling Dystonia or even any type of spasm and even if she had, lower limb dystonia is actually uncommon in adulthood and least commonly originates in isolation of the lower limbs, so it's a very unlikely explanation when compared to the more common ones.
MS is actually actually one of the many secondary causes of Dystonia, Dystonia is basically a general term for a large group of movement disorders that vary in their symptoms, causes and progression. There are different types of Dystonia but the most characteristic symptom pattern with most forms of dystonia is twisting, repetitive movements that affect the neck, torso, limbs, eyes, face, vocal chords, and/or a combination of these muscle groups.
I'm going to post this, unlike my other deleted attempts trying to understand......hope it helps somehow :D
